CHARLES J. ELLSWORTH AND ANSON O. ALEXANDER, OF PENACOOK, NE? HAMPSHIRE.

INHALER.

SPECIFICATION forming part of Letters Patent No. 425,765, dated April 15, 1890.

Application filed J 11119 2O, 18 8 9.

To all whom it may concern.-

Be it known that We, CHARLES J. ELLs- WORTH and ANsoN C. ALEXANDER, citizens of the United States, residing at Penacook,

in the county of Merrimac and State of New Hampshire, have invented certain new and useful Improvements in an .Inhaling Apparatus, of which the following is a specification. y

This invention relates to apparatus for inhalingheated air-for medicinal purposes.

The object of the invention is to provide an apparatus forreceiving fresh air and heating the same before it passes thence'into an I5 inhaling-tube.

The invention will be fully set forth in the following specification and claim, and clearly illustrated in the accompanying drawings, forming an inseparable part thereof, of

20 which Figure 1 is a sectional elevation of the apparatus, showing a lamp for furnishing heat; and Fig. 2 represents a sectional plan of same.

Similar reference -letters indicate corresponding parts throughout both views.

To carry the invention into practice we provide the exterior case A with two interior shells, respectively, B O, the latter within the former. The exterior case has two or more,

openings connecting with an air-compartment D, formed by the partitions a ct,to the latter of which (the partition a) are secured the interior shells B C.

Theopenings in the case A, above referred to, are'provided with suitable covers A, and when desired these are opened or removed, and any drug or herb with which it is intended to impregnate the air to be inhaled from 4 the apparatus may be placed upon the bottom a of the air-compartment D, or in suitable dishes within said compartment. A hollow nipple'R is also attached to the exterior case A, connecting with said compartment D, to which the fresh-air-receiving tube R is secured, and the air entering said tube passes upward through openings D into the heating-chamber E, and thence through the hollow casting S by means of its nipple s 5 into the inhaling-tube S.

Serial No. 315,021- (No model.)

In order to know to what degree of heat the air is when being inhaled by a patient, a thermometer 3' may be secured in some c011- venient manner to the casting S, as seen in The said casting S passes through an opening formed in the top of the case A and enters the heating-chamber E, as shown, and the tops of the exterior case and the interior shells B C are formed,preferably, convex, as shown. i

The heat for the apparatus may be obtained from gas, or a lamp X may be placed under the compartment D and its chimney Y extend upward through said compartment, so that the greater part of heat will enter the interior shell 0.

The chimney Y is provided with perforations T for the circulation of air, and the necessary draft for the lamp is received by means of perforations a formed in the lower part of said exterior case A, and this, together with any unpleasant odors from the lamp, passes through tubular passages D in the compartment D into the foul-air chamber F, and is conducted to a safe distance by 7 5 means of the hollow nipple T and the conductor T, attached thereto.

Having described our invention, what we claim, and desire to secure by Letters Iatr ent, is

A hot-air-inhaling apparatus comprising a cold-air compartment having two or more covered openings in its side and a tube for feeding fresh air therein, an interior heatingdrum, an air-heating chamber surrounding said drum, having an outlet at its top, to which is attached an inhaling-tube, and means for admitting air at its bottom from the said cold air compartment, and a foul-air chamber surrounding said air-heating chamber connecting with a tube or pipe at the top of said apparatus, all combined and arranged substantially for the purpose set forth.

In testimony whereof we affix our signatures in presence of two witnesses.
